My son just moved to Hawaii and we will be visiting him in a couple of months. On the return route we decided to stop in Orange County and visit DL for a couple of days. We will be staying in Newport Coast from Monday to Friday and at the moment plan on heading to DL twice (probably Tuesday and Wednesday) while we are there. I noticed during this week it'll be grad night most of those evenings. Will grad night impact daily visitors in anyway? Will part of the park be closed down during the evening hours for this grad night event? What will the crowds be like? One more question, this is our first visit to DL, should I purchase a "2 day-1 park per day tickets" or a "1 day hopper pass". Can I see most of the main attractions in both parks in 1 full day or do I need both days? Thanks.
